             Transmission Control Protocol (TCP) YANG Model
                     draft-scharf-tcpm-yang-tcp-00

Abstract

   This document specifies a base YANG model for TCP on devices that are
   configured by network management protocols.  The YANG model follows
   the standard TCP-MIB [RFC4022].

1.  Introduction

   The Transmission Control Protocol (TCP) [RFC0793] is used by several
   control and management protocols in the Internet.  Therefore, TCP is
   implemented on network elements that can be configured via network
   management protocols such as NETCONF [RFC6241] or RESTCONF [RFC8040].
   This document specifies a YANG data model [RFC6020][RFC7950] for
   configuring and operating TCP on network elements that support YANG
   data models.

   Many protocol stacks on Internet hosts use other methods to configure
   TCP, such as operating system configuration or policies.  Such TCP
   stacks typically cannot be configured by network management protocols
   such as NETCONF or RESTCONF.  This document only applies to network
   elements that use YANG data models.

   This document is related to other standardization efforts.  A
   Management Information Base (MIB) for the Transmission Control
   Protocol (TCP) has been standardized [RFC4022], and various managed
   network devices support the TCP-MIB.  A MIB providing extended
   statistics for TCP is also available [RFC4898].  In addition, there
   are also MIBs for UDP [RFC4113] and SCTP [RFC3873].

   This documents defines a YANG data model for configuration and
   operational state of a TCP implementation.  The model focuses on
   fundamental and standard TCP functions.  The model can be augmented
   to address more advanced or implementation-specific TCP features.
